Int the application of my improvement the cartruck frame may be verysimple, and of the usual construction, as seen in the drawing at A A,Figure 1.

Instead of the usual axle-box I employ-two hangers, E,.attached to theframe and extending to the rave B p Between these hangers are placed twoanti-friction rollers, b, which have separate axles, a, Figure 3, fixedin the hangers E E, by being made square at the head,

and tightly held by screw-nuts h.
